In this article, a singularly perturbed convection–diffusion equation is solved by a linear finite element method on Bakhvalov-type meshes. By means of a novel interpolation to the solution, a supercloseness result is obtained on Bakhvalov-type meshes for the first time.

一维奇摄动对流扩散方程在Bakhvalov型网格上的线性有限元方法的超闭合性

在本文中，通过线性有限元方法在Bakhvalov型网格上求解奇摄动对流扩散方程。通过对该解进行新颖的插值，第一次在Bakhvalov型网格上获得了超闭合性结果。
